"The news is not very good, and we have to analyze the situation in light of the decision that has been taken," he said.
He slammed the CAS's move as "unacceptable," specifically pointing to the fact that the Russian athletes who were banned have nothing to do with doping.
Commenting on the ban, Russian Minister of Sport Vitaly Mutko, in turn, pledged more efforts to continue to protect the honor and dignity of Russian athletes right down to lodging a lawsuit with the civil courts.
"I think that efforts will continue to protect the honor and dignity, even if we are late for the 2016 Olympic Games. I think that the time has come for applying to the civil courts," Mutko was quoted by RIA Novosti as saying.
Russia's two-time Olympic champion and pole-vault legend Yelena Isinbayeva, for her part, did not mince words when commenting in her Instagram account on the CAS's ban.
"The hope has finally faded away. May all these 'clean' foreign athletes take a deep breath of relief and win their quasi-gold medals in our absence. People always are afraid of power," she wrote.
She was echoed by Olympic athletics champion Olga Bogoslovskaya, who in an interview with Sputnik harshly criticized the CAS's decision and warned of consequences for the Russian team.
"The decision is awful and it once again shows how politicized the whole system is. I talked to the athletes who survived boycotts in 1980 and 1984 and they said that this ban avalanche may engulf not only Russian athletes but the entire international Olympic movement," she said.
Nikolai Dolgopolov, Vice-President of the International Sports Press Association, in turn, told Sputnik that "the CAS's decision is completely absurd".
"Absolutely innocent people who are 'clean' and do not have a history of doping have been banned from taking part in the Rio Olympics. They are deprived of their civil rights to do what they can. By taking this decision the court in Lausanne has proved its complete incompetence," he said.
Speaking to Sputnik, Italy's Northern League Party deputy Gianluca Pini, for his part, described the ban as a "politically motivated move and a huge geostrategic mistake."
"This is an act of political sabotage against Russia and a sign of fear felt by certain international circles with respect to such political strongman as [Russian President] Putin," he said.
On his Facebook page, sports commentator Yevgeny Slyusarenko drew attention to the fact that in the past six months, the British Anti-Doping Agency has collected about 3,000 suspected doping samples related to Russian athletes, managing to discover just two positive results.
"Only two of 3,000. It is an excellent level of doping rampage in the country, isn't it? Of course, the athletes should be punished, "he wrote sarcastically.
The IAAF first imposed the ban on the All-Russia Athletics Federation (ARAF) last November, then upheld it in June.
"The CAS rejects the claims/appeal of the Russian Olympic Committee and 68 Russian athletes," the court said on its website.
The athletes may submit appeal during 30 days, CAS secretary general stated. However the CAS has emphasized that "the door is open" for the International Olympic Committee to decide on Russian athletes' participation in the Olympics.
